Answer 1

Penjelasan dengan langkah-langkah:

2.

Lim x→3 (x³+6x-6)

= (3)³+6(3)-6

= 27+18-6

= 39

===========================

3.

[tex] lim_{x\to4}( \frac{x - 4}{ {x}^{2} - x - 12 } ) \\ = lim_{x\to4}( \frac{x - 4}{ {x}^{2} - x - 12 } ) \\ = lim_{x\to4}( \frac{x - 4}{(x + 3)(x -4)} ) \\ = lim_{x\to4}( \frac{\cancel{x - 4}}{ (x + 3)\cancel{(x - 4)} } ) \\ = lim_{x\to4}( \frac{1}{x + 3} ) \\ = lim_{x\to4}( \frac{1}{4 + 3} ) \\ = \frac{1}{7} [/tex]

Answer 2

Penjelasan dengan langkah-langkah:

1. lim (x³ + 6x - 6)

x → 3

= (3³ + 6(3) - 6)

= 27 + 18 - 6

= 39

2. lim (x - 4)/(x² - x - 12)

x → 4

= (x - 4)/(x - 4)(x + 3)

= 1/(x + 3)

= 1/(4 + 3)

= 1/7
